. Claims. This invention relates towindow construction,

and particularly to a construction for a metal window; a

It is among the objects of this invention to provide ametal window wherein the sash may easily be installed in or removed from the window frame, and wherein the spaces between the side bars of the sash and the frame are effectively sealed by means which prevent rattling of the It is another object of the invention to provide a window of the above nature wherein the relatively movable surfaces of the frame and sash which normally tend to engage one another have interposed therebetween bearing and lubricating members which prevent the scoring and destruction of these contacting 'surfaces, which would otherwise result from the sliding engagement therebetween.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated in the following claims. In the drawing, wherein there are shown two embodiments of our invention,

Figure 1 is a sectional elevation of a double hung window incorporating our invention;

Figure 2 is a horizontal section of the window I shown in Figure 1, portions thereof being broken away;

Figure 3 is a fragmentary elevation, partly in section of a portion of the window;

Figure 4 is a fr gmentary sectional perspective of a portion of our window; and

Figure 5 is a fragmentary horizontal section of a modified fcrm'of a portion of our window.

Similar reference characters refer to similar parts throughout the various views of the drawmg ferring now to Figure 1, the opening formed by the sliding structure III is framed by an upper frame member H, a lower frame member l2, a side frame member l3 (Figure 2) and another side frame member ,these frame members being joined at their abutting ends in any suitable manner to form an integral frame disposed in the building structure to receive upper and lower window sashes A and B respectively (Figure 1) of a double hung window. v

Upper frame member II is suitably secured to the bottom of a cover channel l5 suitably disposed above the window frame in the building structure, the cover channel being dapted to house sash balances of a conventional nature. Frame II is preferably an extruded section of a non-ferrous metal, such as aluminum, and accordingly comprises a web portion Ila from which extend up,-, wardly flanges l6and l1, and from which extend downwardly a pair of spaced stop beads l8 and I9 which form between them a sash channel 20. Outer bead l8 has formed integrally therewith a plurality of projections-Ma and I 8b, which form a suitable chamber to receive and hold a resilient metal Weatherstrip 29, one side m of which is arranged to bear against the outer upper edge of the upper sash bar 22 of sash A. When inits uppermost position, upper sash bar 22 fits within sash channel '20 so that its upper inner edge engages stop bead |9 by reason of theresilieney of weather strip 2l. Upper sash bar 22 is'thus firmly held within its channel 20 against stop bead IS, the weather strip not only effectively sealing the interior against the weather, but also comprising an effective anti-rattle device.

As hereinbefore noted, upper frame member ll is an extruded section and therefore flanges IS and I1 and stop beads l8 and i9 ar together with the body Ila of the frame membe integral. As is better shown in Figure 2, sideor mullion. frames I3 and I4 are also extruded sections, also preferably of a non-ferrous metal, .such as aluminum, for example. Frame I3 is generally U- shaped and thus comprises a web, of body portion l3a from which extend legs 23 and 24, having respective flanges 23a and 2la,1which may be attached to building structure Ill inany suitable manner. A stop head 25 is preferably'formed integrally with the frame, and extends therefrom generally in the plane of leg 24. Bead 25 includes DIOJBCtlOIlS 25a and 25b, which form with portions of web IS a suitablechamber for retaining a weather strip 26 preferably formed of a resilient metal. provided with a shoulder 21, and a projection 28, which together comprise a 29a adapted to fit 29b which rests against shoulder 21. A screw 30 may be used, if desired to hold stop head 29 in place. Bead 29 has formed thereon projections similar to those provided on bead 25, which suitably retain a weather strip 3| similar to -weather strip 26.

The web l3a of frame l3 has preferably formed indicated at 33. Preferably II truded from non-ferrous metal such The other leg 23 of frame It is suitable seat for a detachable stop bead 29 provided with a groove over projection 28, and a leg removedandumn flbe sectionsothatitslegsllandllfltinchannel placeinchannalllinframeitandacorreorgrooveflinframeweblia.

These several beads aresubstantiallysimilartothoseextending from frame l3, and thus include weather strips .48 and IQ, and bearing and lubricating elements 5! and II, the disposition and action of which are thesameasdescrlbedwithrespecttothoseon frame ll. Thus, frame ll includes channels .similartochannels 42 and Binframe ii for the reception. of sashes A and B of the double hung window.

Itwillnowbe seenthatwhensashesAandBareclosed,their upper, lower and side sash bars 22, Ii and ll, respectively, all enga e weather strips. and thus the window is effectively sealed about its periphery.

Members ll and II intherearsurfacesofbeadsll and 45 respectively, similarly facilitate sliding operation of upper sash A.

Further to perfect the seal, we provide, as is shown in Figure 3. a sumlemental sealing strip generally indicated at 51. Strip 1, which is also preferably formed of the zinc-antimony -alloy, includes a doubled over bottom flange 5!, which issecuredasbyascrewlitothebottomsurface iicofiowersashbarilseealsol 'igureslandl Sealingstrip 51 (Figure 3) alsoincludes auupwardlyextendingflangeblwhichisdisposedbetween the web Ila of side I4 and the outer side.

(Figure 2) is disposed in the B,andthushasaflange62lyinginchannelfl between frame web lid and the sash side bar. As flanges 6| and I of supplemental weather strips 51 and I respectively are resilient, and are biased outwardly of the sides of the sash, they not only are effective as weather seals, but also act to hold the window sash B in proper operative position. By reason of the fact that these supplemental weather strips are formed of the zinc-antimony alloy referred to, they readily slide against the non-ferrous frames II and I4 without scoring the frames.

A similar strip I It may now be seen that we have provided a outer side of sash able that the sash carry the bearing and lubricating strip, rather than the stop bead. To this end we provide the structure shown in Figure 5, wherein the side or mullion frame l3 has detachably secured thereto a bead 63 as byscrews 64. Sash B, in this instance, has a sash side bar 65 provided with a thickened portion 66 in which a groove 61 is formed. Groove 61 carries a sealing and lubricating element 68 similar in structure and purpose to element 40, shown in Figure 2, element 68 riding against the front surface of bead 63 as the window sash slides up and down.

It will be obvious, of course, that the other sash side bars are similarly provided with lubricating strips.

It is of course to be understood that in so far as the removability of the sash is concerned, the invention is applicable to window constructions wherein the-sash and frame are formed entirely of metal, or wherein portions of each, or both, may be formed partly of metal and partly of wood. As to preventing rattling of the sash, the material of the frame and sash is not important. In so far as the lubricating of the relatively movable parts of the frame and sash is concerned, it is of course important that the adjacent relatively movable surfaces are of such metal that the friction created by such relative movement will cause a scoring or abrasion of said surfaces.

Accordingly, it will appear that we have provided a window that accomplishes the objects hereinabove set forth in a thoroughly practical and efficient manner.

- As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth, or shown in the accompanying drawing, is to be interpreted as illustrative and not in a limiting sense.

We claim:

1. As an article of manufacture, a parting strip for a double hung window comprising a substantially U-shaped member having a pair of thickened portions, said thickened portions having longitudinal grooves or slots cut therein adapted to receive and support outwardly facing sealing and lubricating elements.

2.
